Viscosity Measurement and Correlation of Unloaded and CO₂-Loaded 3-Amino-1-propanol Solution

This paper reports new viscosity data for unloaded and CO

aqueous 3-amino-1-propanol (3A1P) solutions. For the unloaded system, experiments
were performed over the whole concentration range at temperatures between 298.15
and 373.15 K. In the case of a CO

available methods from the literature.
